CRANE;

Application 'filed June 10, 1927. Serial No. 197,818.

This invention relates ;to an improved crane for use over a restricted central space and is particularly adapted for repair work on automobiles, as one man can remove, v

5 replace or adjust heavy parts that at present require the servicesof several men.

The deviceis constructed so that it can be supported on the side frames of a chassis and thus bridge the chassis and it can be made compact enough to it under the cowl of an automobile. This position enables it to be used for lifting the transmission on automobiles or tractors, for lifting the front of motors for changing timing gears, for removing orreplacing'fly wheels on motor cars without removing the motors, for pulling out and replacing worm drives in cars, and for other uses .in this connection.

In handling some parts, as in seating 29 transmission cases, the placing requires, a

forward and rearward adjustment in fitting the parts, and the device is, for this reason made so that the hoisting means has 'a limited movement in a direction longitudi- 5 nally of the car, that is, laterally relativeto the crane.

The invention is illustrated in the accompanying drawing, in which Figure 1 is a face view of a crane made accordingto my invention and Figure 2 is a side view thereof.

The device is made of a main frame which is arched and I show a frame made in the form of a shear with the shear legs 10 and llpivoted together at the top, as at 12. The bottoms of the shear legs are adapted for securing to the side bars 13 of a chassis illustrated shows slotted clamp with the chassis bars 13 in the various widths of cars. The clamping is done by suitable means such as the screws 17 The shear is supplied with a suitable hoist and I illustrate the cable 18 with a suitable' grappling device 19, the cable passing over 5 drum 21 operated by a handle 22. A ratchet 23 secured to the drum and a pawl '24 secured to the arm 11 hold the drum in position. The grappling device 19, is, of

the pulley 20 and raised or lowered by the course, of various kinds to meet the requirements of the ob and to conformjto the parts to be elevated.

i The cable and the pulley 20 are usually I on the shear, the shaft 26 being supported thereby and the pulley being slidable on the I shaft. The clevis is wide enough to allow a material sliding of the pulley thereon.

The crane can thus be used for not only raisingand lowering parts of the engine mechanism but also for moving themforward or back to fit them together when such movements are necessary.

The device is compact and permits one man to lift elements weighing many hundreds of pounds which at present require the services of two or three men.

In the drawing the dotted outline indieats a transmission case at 27 and a part of a cowl of an automobile at 28. The usual size of the device is of such dimensions as to allow it to be easily inserted under the cowl of a passenger car or a truck. It is usual to attach the pulley 20 and its supporting means to one of the shear legs ing part of the cable 18 is central of the shear, therefore, it is in the centre of the chassis frame which is the position of most of the parts that require. adjustment. This, however, does not interfere with the use of the crane on elements to one side of the centre.

I claim 1. A crane for use on automobiles comprising a pair of hinged shearlegs that are curved to 'fit under the cowl of the automo bile, means on the ends ofthe legs for securing them, to the chassis of a car, and a hoisting mechanism on the shear.

2. A crane for use on automobiles comprising an arched frame'with slots on the outer sides at the bottom of the arch said slots to embrace the inner sides of the chassis of the automobile, and a hoisting and holding means secured to the crane. 7' 3. A crane for use on automobiles compris ing a pair of hinged shear legs having slots on the outersidesat the bottom, means for clamping the frame of the chassis in said slots, a pulley suspended from one of said legs, a hoisting cable passing over the pulley,

pawl and ratchet for holding the cable and a handle i011 the ratchet. l s

4;. Abrane for use on automdbi'les "comprisin a pair of hinged shear legs having slutsnflie outer sides Wt the bdttom, means forlclamping the framed the chassis in said said pulley e-for the raising of elements of the fear frames;

-- -5..A crane nutoinobiles econ iprising gm pair of shearflegs hinged together atithe' meehenism between the chassis top, a elainp secured to the bottom of each leg :at least oneef said ehtmpsheing pi? oted to its leg, and a heisting means supported'hy and between the'shearlegs. V *6. A crane for antomobiles mmprieingwii pair of shear zlegsrhiuged tngether :et the top,

a clamp secured to the bottomiofiflch leg, at least one of said clamps being pivoted to leg, a' pawl and ratchet on one of said legs, afhan'dl'e' for operetingthe ratchet, a, 'cable operatedby the handle: and a pulley onthe crane over which the eablefpasses.

In testimony whereof I a-flix mysigneture.
